应用交流阻抗谱中的Kramers Kronig变换对受海水长期侵蚀的混凝土和钢筋分别进行了研究 .混凝土和钢筋的稳定性可用K K变换值与实测值之间相对偏差的大小来进行衡量 .随着海水侵蚀时间的增加 ,混凝土和钢筋的稳定性越来越差 .在同样条件下 ,掺粉煤灰混凝土的稳定性优于普通混凝土
The Kramers Kronig transformation in AC impedance spectroscopy was used to study the long-term erosion of concrete and rebar by seawater respectively.The stability of concrete and rebar can be measured by the relative deviation between KK transform and measured value.With the seawater erosion With the increase of time, the stability of concrete and rebar is worse and worse.Under the same conditions, the stability of concrete with fly ash is better than ordinary concrete
